New for Cheng Technology Co., Ltd. is excited to introduce a brand-new series of economical miniature vacuum pumps — the VAT line. Many existing and potential customers have already shown great interest, with several reaching out to express strong purchasing intentions. However, we would like to clarify that while the VAT model is cost-effective, it is not a replacement for our high-end miniature vacuum pump series. The VAT is essentially an economical version of the VLK series, but there are key differences that make it more suitable for specific applications.
First, the functions differ significantly. The VLK series features a brushless motor with imported high-grade components, built-in control circuits, PWM speed control, FG motor feedback, and PLC compatibility. This allows for closed-loop control, making it easy to adjust motor speed and, in turn, regulate flow, vacuum level, and other parameters. It supports advanced functions such as constant current and constant pressure operation, with stable performance even under varying loads. In contrast, the VAT series lacks these advanced controls. It only offers limited voltage or valve-based regulation, with a narrow adjustment range and lower load capacity compared to the VLK.
Second, quality varies greatly between the two. The VLK series uses high-grade double ball bearings, ensuring long-term stability and reliability under heavy-duty conditions. On the other hand, the VAT series uses oil bearings, which may wear out faster and result in shorter overall lifespan.
Third, anti-jamming performance is another key difference. The VLK series uses high-quality brushless motors that generate minimal electromagnetic interference, reducing the risk of system crashes or malfunctions. The VAT series, however, may produce higher voltage spikes during operation, potentially causing issues with control circuits or LCD displays.
Fourth, noise levels differ. The VLK can operate continuously without significant changes in noise levels, making it ideal for 24/7 use. The VAT, on the other hand, may become noisier over time due to the drying of oil bearings, leading to increased operational sound.
Fifth, the expected lifespan of the VLK series is significantly longer. Under full load, the VLK can run for over 6,000 hours, with testing still ongoing. The VAT, by comparison, has a much shorter lifespan, typically around 1,000 hours.
Lastly, warranty terms also differ. The VLK series comes with a one-year warranty, while the VAT model is covered for only six months.
In conclusion, when selecting a miniature vacuum pump, it's important not to focus solely on price. Customers should consider factors like quality, reliability, and long-term performance to choose the most suitable option for their needs. At Cheng Technology, we're committed to providing solutions that match your specific requirements, whether you need an economical option or a high-performance unit.
